Quarterback Tom Savage suffered a hit during the Houston Texans' game against the San Francisco 49ers Sunday and briefly was checked out by doctors on the sideline, returned, then left again and was ruled out for the game.
After the contest, head coach Bill O'Brien passed the blame:
As for reports of Savage spitting up blood or having a seizure, here's what was reported:
It's unclear what exactly happened to Savage, but the quarterback did what several believe to be the "fencing response", which is common in combat athletes directly after a knockout. If Savage did indeed suffer a concussion, there will have to be a major response by the NFL as to why he was allowed back on the field with several fail-safes used to try and prevent such an action.
